IMPROVEMENT IN STEAM-STILLS.

Specification forming part of Letters Patent No. 180,260, dated July 25,1876; application filed November 22, 1875.

To all whom it may concern:

Be it known that I, ADOLPHUS F. W. NEY- NABER, of New York city, countyofNew York, State of New York, have invented an Automatic Steam-Still,of which the following is a specification The object of my invention isa better and more perfect separation of alcohol (spirit) from the waterand fusel-oil contained in the crude distillate of mashi. 6., whiskyv byavoiding, in the first place, the evaporation of such water andfusel-oil, and thereby simplifying the whole process, inasmuch as aseparation of such water and fusel-oil will not be required in thecondensation of the vapors afterward. The main feature of this inventionis to so construct the apparatus that the highest temperature is overthe whisky, and at the outlet of'the vapor, but not underneath thewhisky, nor the whisky brought-into direct contact with the pipesinclosing the live steam.

The object of this invention is accomplished by putting a steam-coilinto an ordinary still over the whisky, extending the heating-pipes allover the surface of whisky, but leaving sufficient space between thebottom of the still and the steam-pipes to avoid a direct contact of thewhisky with the steam pipes above.-

An oblong still is so constructed that the outlet for vapor is at thesame end where the whisky is forced into the apparatus by means of apipe giving out a spray falling into channels, so as to divide thewhisky more equally over the surface, and having on the same end thesteam entering a pipe coiling to the opposite end, by which arrange.

ment steam will pass like a serpent in the same direction as thewhisky'flows, as shown in the vertical longitudinal section, Figure andin the horizontal longitudinal section,

Fig. 2, indicated in Fig. l by lines 00 x of the accompanying drawing;or an oblong still may be constructed without compartments, and withoutspray-pipe B, allowing a certain charge to enter the still through athrough pipe E, which should be provided, for such purpose, with astop-cock, to retain the whisky until exhausted.

If an oblong still is put into such a position as to bring bed A inlevel, and one or two barrels or tanks filled with whisky will beconnected with pipe B, cock 0 opened sufficiently, aspray of whisky willbe -forced through holes a of pipe'B on bed A, and will, when it reachesthe opposite end of a bed of sufficient length, be deprived of itsalcohol, if the flow of whisky has been properly regulated in proportionto the length of bed A, and the proper heat has been applied byregulating cock G.

The water and fusel-oil will run off through pipe E, of which there maybe one or more, Fig. 2.

Cock 1) is used for cleaning pipe E. In this case there should be also astop-cock for pipe E,

so that the'flow of liquid through E may be stopped, if desired.

It will be evident that the whisky, as it is tained on the bed orbottom, in consequence of the lower temperature of the bed, while anyrecondensation' of alcohol once transformed into vaporis prevented inthe still through the heat radiated and conducted from the heatingapparatus D to outlet F, carrying off the vapor of alcohol.

I claim as'my invention 1. The combination of distilling-chamber A,having one or more liquor-outlets, E, and a liquor-inlet, the steam-pipeD in the upper part of the chamber, and above the surface of the liquorin the chamber, and having an inlet near the liquor outlet oroutlets,whereby only surface-distillation is effected, as set forth.

2. The combination of chamber A,having liquor-outlet and longitudinaldivisions, with perforated liquor-inlet and inclosed steampipe D abovethe surface of liquor in the still, as and for the purpose set forth.
